Pushrod Length?
I'm doing a C/H/I swap on my 2000 C5 5.7,the heads are milled.035 and will be using .051 head gaskets, the cam's base circle is .002 smaller than the stock cam. I've read the stock pushrods are 7.380, so if I subtract the mill amount it comes out to a 7.345 length. The sizes closest to that is 7.350 and 7.365 which length would be the one to buy. The rockers have a trunnion kit and the block has not been decked,

Don't speculate on this a as it's too critical and can be catastrophic if something is off. Get it together and measure with a push rod length checker, they are cheap and easy to use. You spent way too much money and time to not be 100% sure everything is exactly correct.

I would still measure, lifters and decked heads can change the measurement.
